When Zeppelin the hedgehog was brought to a local wildlife rescue centre in Scotland on Sunday, it was not because he was overweight.

In fact, Zeppelin was in pain from air inflating his body to the size of a beach ball after he was likely hit by a vehicle, according to the Scottish SPCA.

"Zeppelin is suffering from 'balloon syndrome'," said Colin Seddon, a manager at the National Wildlife Rescue Centre in Fishcross. "It's likely that he's been clipped by a car, puncturing a lung and causing air to become trapped under his skin."

Animal rescue officer Louise Hume was shocked to see the enlarged hedgehog when she went to pick up the animal after a member of the public spotted the injured creature.
